Safety in application

PVG 120 Proportional Valve Group
All makes and all types of control valves (incl. proportional valves) can fail, thus the necessary protection against the serious consequences of function failure should always be built into the system. For each application an assessment should be made for the consequences of pressure failure and uncontrolled or blocked movements.
To determine the degree of protection that is required to be built into the application, system tools such an FMEA (Failure Mode and Effect Analysis) and Hazard and Risk Analysis can be used.
FMEA – IEC EN 61508
FMEA (Failure Mode and Effect Analysis) is a tool used for analyzing potential risks. This analytical technique is utilized to define, identify, and prioritize the elimination or reduction of known and/or potential failures from a given system before it is released for production. Please refer to IEC FMEA Standard 61508.
Hazard and risk analysis ISO 12100-1 / 14121
This analysis is a tool used in new applications as it will indicate whether there are special safety considerations to be met according to the machine directives EN 13849. Dependent on the determined levels conformity this analysis will detirmine if any extra requirements for the product design, development process, production process or maintenance, i.e. the complete product life cycle.
Warning
All makes/brands and types of directional control valves – inclusive proportional valves – can fail and cause serious damage. It is therefore important to analyze all aspects of the application.
Because the proportional valves are used in many different operation conditions and applications, the manufacturer of the application is alone responsible for making the final selection of the products – and assuring that all performance, safety and warning requirements of the application are met.
The process of choosing the control system – and safety levels – is governed by the machine directives EN 13849 (Safety related requirements for control systems).

Order specification

Ordering of modules for oil flow exceeding 180 l/min [47.6 US gal/min]

Modules for pump with fixed displacement
1. Ordering: Order accessory module 155G6035, main spool D, and pump side modules 155G5027 /
155G5028 / 155G5029.
2. Conversion: In open center systems a max. oil flow exceeding 180 l/min [47.6 US gal/min] can be
achieved by changing the following parts in the pump side and basic modules:
Open center pump side module
•
– Pressure adjustment spool – The springs behind the pressure adjustment spool – The plug behind the pressure adjustment spool Parts from kit 155G5035 may be used.
Closed center pump side module (A closed center pump side module can be changed into an
•
upgraded open center pump side module by means of kit 155G5035.) Basic module
•
– Spring behind pressure compensator – The plug behind the pressure compensator

Order Form
